My guess is the shell is interpreting the "%" character in some way.
Try escaping it like so ..
  Reads/sec is \%.f "

but note that sometimes you need to escape a few times, as it might be
some other level in the process that needs the backslash to appear
intact.  Try with two or even three backslashes like so..
  Reads/sec is \\\%.f "

The most number of backslashes I have needed in a similar situation was five!
